Objects and attributes
This diagram shows the system analyzing objects, including people, and assigning attributes that can be stored and searched.
Patent
Flock's own patent describes sorting people by sex, race, clothing, height, and weight.
Flock cameras are sold as license plate readers. Flock's own patent describes something bigger: video analysis that identifies people and objects, classifies attributes like "male, female, race," clothing, height and weight, stores video with time and location, and lets an operator search those records by attribute.
A patent is not proof that every feature is active in Casa Grande today. But the people searches in the released logs run against exactly this kind of capability, and Flock has said its plate cameras can become video cameras through a cloud software update.
US Patent 11,416,545 B1
"Male, female, race." Clothing. "Height and weight."
Those are the patent's own examples of the attributes the system assigns to a person it sees, so that an operator can later search for "a male wearing blue jeans within this geographic zone."

Why the patent matters
Companies patent technology they are using, building, or preparing to sell. Treat these excerpts as product direction, not speculation. With AI moving quickly, this technology may already be in use elsewhere or close to deployment.

Searches for people
22
Officers searched the cameras for people by gender and clothing.
Searches for a "male" or "female" in four months. Every search was allowed.

Microphones
31
The "no audio" answer skips the 31 gunshot microphones.
The 31 gunshot-detection devices are microphones. A microphone cannot detect a gunshot without recording the sound around it, and Flock plans to have them listen for human distress.

Schools
May 4
Flock is in the elementary schools.
The agreement never defines "authorized users," never bans facial recognition or AI analytics, and never requires telling parents.

Bottom line
The capability is patented. The people searches are in the logs.
Casa Grande residents deserve to know exactly what the system can collect, who can search it, and what rules stop abuse.
